BOX-LOOP FOR HARNESS.

SPECIFICATION forming part of Letters Patent No. 231,393, dated August 24., 1880.

Application filed February 14, 1880.

To all whom it may concern Be it known that I, JOHN G. BRIGH'IMAN, of Fall River, in the county of Bristol, in the State of Massachusetts, have invented a new and useful Improvement in Box-Loops for Harnesses; and I do hereby declare the following to be a specification thereof, reference being had to the accompanying drawings.

Like letters indicate like parts.

Figure 1 is a perspective view of my invention. Fig. 2 is a transverse section of the same.

My invention relates to box-loops for harnesses, and is an improvement upon the invention described in the specification of Letters Patentof the United States No. 216,256, issued to me, said John O. Brightman and one John B. Burrell, June 10, 1879, for an improvement in box-loops for harnesses.

My improvement consisls in folding the sheet metal to form the frame with two boxlike compartments, instead of the single boxshaped compartment and flanges, as specified in said Letters Patent No. 216,256.

The sheet metal is bentlongitudinallyin the shape shown in cross-section in Fig. 2, forming the two rectangular compartments A and (1, with the narrow shank a connecting the two. The cheek B is cemented to the sheet metal before bending, and is folded with and upon the frame A in rectangular shape, the edges of said cheek extending to the shank a on each side. The box-loop D is folded into rectangular shape and slid longitudinally upon the frame 0, its edges also extending to the shank a on each side. The compartmentG occupies about one-half of the interior space of the box-loop D. When all the parts are in position I insert a bar into each of the compartments A and G,

and into the box-loop D, to preserve their shape, and by a suitable press I compress the Whole together, thereby securing them all in place. The bars are then withdrawn.

By this improved construction I obtain three interior spaces for the insertion of the cheekstrap. Instead of passing the strap through the compartment A double, as heretofore, I pass only one thickness of the strap through said compartment and the other portion through the compartment 0, while in returning the outer end of said strap I tuck it into the box-loop D. I thus can bring the buckles of said strap more snugly against the top and bottom of the metallic frame A (3. By this construction lam able to make the cheek B much thinner, as the compartment A is made of suffieieutsize to receive only one thickness of the strap.

The blinder-iron is to be fastened by slotted ears in engagement with the flange, as described in said Letters Patent, except that I prefer to pass said slotted earsdirectly through the shank a.

I have described said invention above as adapted to a bridle; but it is equally applicable to other portions of harnesses where box-loops are used.

I claim as a novel and useful invention and desire to secure by Letters Patent- The sheet-metal frame folded into two rectangular compartments, A O, connected by a shank, a, in combination with the cheek B and box loop D, substantially as specified.

JOHN G. BRIGHTMAN.
